• 2. Intent and purposes of districts.

  	RESIDENTIAL DISTRICTS are intended to allow orderly development of residential dwellings designed to complement the natural features of the land, to promote suitable placement of buildings and related facilities in relation to the site and surrounding areas, with adequate living space and open space, to avoid overcrowding of land, to encourage good design, to avoid overburdening municipal facilities, and to insure compatibility with the immediate neighborhood and with the natural environment.
  		R-10 DISTRICT is a residential zone with minimum lot size of ten thousand square feet (10,000 ft. 2 )

Other than prohibited uses, all proposed uses in the TC District are subject to special use permits and design review. [Added 10-27-2004 ]
  	INDUSTRIAL DISTRICTS are established to encourage intensive industrial and business activities, with proper safeguards for protecting nearby residential areas and environmentally sensitive areas.
  	HEAVY INDUSTRIAL I-H is established to provide for levels of noise, vibration, smoke, odor and other evidence of industrial activity commensurate with State and Federal standards and other performance standards that may be set by the Town.
  	LIGHT INDUSTRIAL I-L is established to provide for a lesser level of noise, vibration, smoke, odor and other evidence of industrial activity commensurate with performance standards that may be set by the Town.
  	WATERFRONT DISTRICT WD is established primarily for businesses catering to marine and marine-related activities.
  	OPEN SPACE AND PUBLIC LANDS OS is established for all lands which shall be dedicated to open space, recreation, conservation, or public uses.

  • b) The provisions herein governing the development and use of inland and tidal land subject to flood hazards shall be minimum provisions, shall take precedence over any other conflicting laws, ordinances, or codes, shall not impair or remove the necessity of compliance with any other applicable laws, ordinances, or codes and shall consider any flood plain management programs in neighboring municipalities.
• 2. Applicability.
  • a) All lands determined by the Building Official to be within Special Flood Hazard Areas and flood fringe lands shall be subject to the procedures and regulations established in this section.

The office of the Portsmouth Building Official is responsible for floodplain management. The FIRM and FIS report and any revisions thereto are incorporated herein by reference and are on file with the Building Official of the Town of Portsmouth.

    [Amended 2-25-2019 by Ord. No. 2019-02-25]

• 3. Administration.
  • a) Provisions of this section of the ordinance, including plan review for compliance, record keeping, enforcement and coordination with State and Federal agencies are administered by the Portsmouth Building Official or his/her designee in reference to RIGL § 23-27.3-108.1.
  • b) Violations of flood hazard regulations are administered per ARTICLE XVI of this ordinance in reference to RIGL § 23-27.3-122.3.
  • c) All proposed construction or other development within a Special Flood Hazard Area shall require a permit.

Development projects include any filling, grading, excavation, mining, drilling, storage of materials, temporary stream crossings. If the construction or other development within a Special Flood Hazard Area is not covered by a building permit, all other non-structural activities shall be permitted by either the Rhode Island Coastal Resources Management Council and/or the Rhode Island Department of Environmental Management as applicable. Therefore if another State agency issues a permit, the local building official must have the opportunity for input and keep a copy of the respective permit in their files.
  • e) If the construction or other development within a Special Flood Hazard Area is not covered by a building permit or other approved permit application, a flood hazard development permit shall be required. The application for a flood hazard development permit shall be submitted to the Portsmouth Building Official and shall include:
    • (1) The name and address of the applicant;
    • (2) An address or a map indicating the location of the construction site;
    • (3) A site plan showing location of existing and proposed structures, sewage disposal facilities, water supply facilities, areas to be cut and filled, and the dimensions of the lot;

    • (5) A statement as to the type of sewage system proposed;
    • (6) Specification of dimensions of the proposed structures;
    • (7) The specific datum used for all elevations;
    • (8) The elevation (in relation to mean sea level) of the lowest floor, including basement, and if the lowest floor is below grade on one or more sides, the elevation of the floor immediately above;
    • (9) Base flood elevation data for all new, relocated or substantially improved structures;
    • (10) The elevation (in relation to mean sea level) to which the structure will be floodproofed;
    • (11) The description of the extent to which any watercourse will be altered or relocated as a result of the proposed development.
  • f) Prior to the issuance of a building or development permit, the applicant shall submit evidence that all necessary permits and approvals have been received from all government agencies from which approval is required by Federal or State law.
  • g) All permit applications for construction or other development within a Special Flood Hazard Area shall be reviewed to determine whether the proposed site will be reasonably safe from flooding. All new construction and substantial improvements shall:
    • (1) Be designed (or modified) and adequately anchored to prevent flotation, collapse, or lateral movement of the structure resulting from hydrodynamic and hydrostatic loads, including the effects of buoyancy;
    • (2) Be constructed with materials resistant to flood damage;
    • (3) Be constructed by methods and practices that minimize flood damages, and;
    • (4) Be constructed with electrical, heating, ventilation, plumbing, and air conditioning equipment and other service facilities that are designed and/or located so as to prevent water from entering or accumulating within the components during conditions of flooding.
  • h) All new subdivision proposals, including new manufactured home parks, shall be reviewed to determine whether the proposed site will be reasonably safe from flooding. All such proposals shall be reviewed to assure that:
    • (1) They are consistent with the need to minimize flood damage within the flood-prone area,
    • (2) All public utilities and facilities, such as sewer, gas, electrical, and water systems are located and constructed to minimize or eliminate flood damage,
    • (3) Adequate drainage is provided to reduce exposure to flood hazards.
• 4. Reference to existing regulations.
  • a) The Special Flood Hazard Areas are established as a floodplain overlay district. All development in the district, including structural and non-structural activities, whether permitted by right or by special use permit must be in compliance with the following:

    	•	Rhode Island State Building Code (as established under Rhode Island General Law § 23-27.3-100.1)
    	•	Coastal Resources Management Program, Coastal Resource Management Council (RIGL § 46-23)
    	•	Endangered Species Act, Rhode Island Department of Environmental Management (RIGL § 20-1-2)
    	•	Freshwater Wetlands Act, Department of Environmental Management (RIGL § 46-23-6)
    	•	Minimum Standards Related to Individual Sewage Disposal Systems, Department of Environmental Management (RIGL § 46-12)
    	•	Water Quality Regulations, Rhode Island Department of Environmental Management (RIGL § 42-17.1 and 42-17.6 and 46-12)

    Any variances from the provisions and requirements of the above referenced State regulations may only be granted in accordance with the required variance procedures of these State regulations.

  • b) All new and replacement water supply systems proposed for installation in a Special Flood Hazard Area are to be designed to minimize or eliminate infiltration of flood waters into the systems.
  • c) All new and replacement waste water treatment systems proposed for installation in a Special Flood Hazard Area are to be designed to minimize or eliminate infiltration of flood waters into such systems and discharge from such systems into flood waters.

The provisions of this paragraph are reviewed and administered by the Rhode Island Department of Environmental Management (RIDEM).
  • d) All manufactured homes to be placed within a Special Flood Hazard Area shall be installed using methods and practices which minimize flood damage. For the purposes of this requirement, manufactured homes shall be elevated on a permanent foundation such that the lowest floor of the manufactured home is at or above the base flood elevation and be securely anchored to an adequately anchored foundation system in accordance with the provisions of the Rhode Island Building Code. This requirement is in addition to applicable State and local anchoring requirements for resisting wind forces.
  • e) In a riverine situation requiring any alteration or relocation of a watercourse, the carrying capacity of any altered or relocated watercourse shall be maintained. If the watercourse crosses municipal boundaries, the Portsmouth Building Official shall notify the adjacent community, as well as:

    	NFIP State Coordinator Rhode Island Emergency Management Agency 645 New London Avenue Cranston, RI 02920
    	Risk Analysis Branch Federal Emergency Management Agency, Region I 99 High Street, 6th Floor Boston, MA 02110

• 5. Base flood elevation and floodway data.
  • a) Floodway Data - In Zones A, A1-30 and AE, along watercourses that have not had a regulatory floodway designated, the best available Federal, State, local, or other floodway data shall be used to prohibit encroachments in floodways which would result in any increase in flood levels within the community during the occurrence of the base flood discharge.

For purposes of these regulations, the term "special flood hazard area" is synonymous in meaning with the phrase "area of special flood hazard".

  START OF CONSTRUCTION — For other than new construction or substantial improvements under the Coastal Barrier Resources Act (P.L. 97-348), includes substantial improvement and means the date the building permit was issued, provided the actual start of construction, repair, reconstruction, rehabilitation, addition placement, substantial improvement or other improvement was within one hundred and eighty (180) days of the permit date. The actual start means either the first placement of permanent construction of a structure on a site, such as the pouring of slab or footings, the installation of piles, the construction of columns, or any work beyond the stage of excavation, or the placement of a manufactured home on a foundation. Permanent construction does not include land preparation, such as clearing, grading and filling; nor does it include the installation of streets and/or walkways; nor does it include excavation for a basement, footings, piers, or foundations or the erections of temporary forms; nor does it include the installation on the property of accessory buildings, such as garages or sheds not occupied as dwelling units or not part of the main structure. For a substantial improvement, the actual start of construction means the first alteration of any wall, ceiling, floor, or other structural part of a building, whether or not that alteration affects the external dimensions of the building.

  STRUCTURE — For floodplain management purposes, a walled and roofed building, including a gas or liquid storage tank, that is principally above ground, as well as a manufactured home.

  	3.	A travel trailer without wheels, built on a chassis and affixed to a permanent foundation, that is regulated under the community's floodplain management and building ordinances or laws.
  	For the latter purpose, "structure" does not mean recreational vehicle or a park trailer or other similar vehicle, except as described in paragraph (3) of this definition, or a gas or liquid storage tank.

  SUBSTANTIAL DAMAGE — Damage of any origin sustained by a structure, whereby the cost of restoring the structure to its pre-damaged condition would equal or exceed fifty percent (50%) of the market value of the structure before the damage occurred.

  SUBSTANTIAL IMPROVEMENT — Any repair, reconstruction or improvement of a structure, the cost of which equals or exceeds fifty percent (50%) of the market value of the structure either, a) before the improvement or repair is started, or b) if the structure has been damaged, and is being restored, before the damage occurred. For the purposes of this definition "substantial improvement" is considered to occur when the first alteration of any wall, ceiling, floor or other structural part of the building commences, whether or not that alteration affects the external dimensions of the structure. The term does not, however, include either 1) any project for improvement of a structure to comply with existing state or local health, sanitary or safety code specifications which are solely necessary to assure safe living conditions or 2) any alteration of a structure listed on the National Register of Historic Places or a State Inventory of Historic Places.

  VARIANCE — A grant of relief by a community from the terms of the floodplain management ordinance that allows construction in a manner otherwise prohibited and where specific enforcement would result in unnecessary hardship.

  VIOLATION — Failure of a structure or other development to be fully complaint with the community's floodplain management ordinance. A structure or other development without required permits, lowest floor elevation documentation, flood-proofing certificates or required floodway encroachment calculations is presumed to be in violation until such time as that documentation is provided.

• 10. Mandatory site design standards.

  Environmentally sensitive site design standards (best management practices) are required for all permitted uses, whether by special use permit or otherwise, in the Watershed Protection District. These standards are developed to optimize water quality, as opposed to technical "make do" compliance.

  The following measures shall be required, as applicable and feasible, in the best interests of protecting water quality:

  • a) Vegetated buffers must be maintained or planted around all critical environmental areas, including reservoirs, and their tributaries. Vegetated buffers ninety-five feet (95') in width shall be composed of the following:
    • (1) A strip of land fifteen feet (15') wide starting at the edge of the pond or stream bank, which shall be comprised of mature trees and shrubs that are to remain undisturbed. Outflow from subsurface drains must not be allowed to enter or pass through this area.
    • (2) Next to the fifteen foot (15') strip, a strip of land at least sixty feet (60') wide, which shall be comprised of trees and shrubs that may be managed as necessary. Outflow from subsurface drains must not be allowed to enter or pass through this area.
    • (3) Thence a strip of land at least twenty feet (20') wide, which shall be comprised of the devices designed to convert concentrated overland or piped flow to uniform shallow sheet flow.
    • (4) Specifications for these buffers shall be according to a publication entitled "Riparian Forest Buffers", U.S. Department of Agriculture. 1991. Trees and shrubs employed shall be selected based on a publication entitled "Sustainable Trees and Shrubs for Southern New England", University of Rhode Island, 1995.
  • b) Surface water runoff shall be directed toward areas covered with vegetation for surface infiltration.
  • c) Surface water runoff shall be directed toward the lesser restricted district where the property is located within two (2) or more districts, as feasible.
  • d) Parking lot controls, including pervious surfaces and drainage facilities shall be employed.
  • e) Buildings and impervious surfaces shall be set back at least one hundred fifty feet (150') from the inland edge of the reservoirs and their tributaries.
  • f) Minimize tree removal: Applicant must demonstrate why each area must be cleared. Priority shall be given to maintaining established trees. Existing natural buffers, as in 10.a) above, shall be maintained.
  • g) All grading, filling, excavation, tilling, or chemical use shall be set back at least one hundred feet (100') (or RIDEM regulations, whichever is greater, or per the R.I. Right to Farm Act if applicable) from the inland edge of the reservoirs and their tributaries.
  • h) Areas to be disturbed within three hundred feet (300') of any water body or wetland shall be clearly marked on approved plans. On site, prior to any construction activity, the areas to be disturbed shall be clearly delineated with stakes and ropes, or other appropriate material, and the downhill border of said area lined with staked hay bales in accordance with the Portsmouth Soil Erosion and Sedimentation Ordinance.

• 1. Applicability. For the purpose of this section a substandard lot of record lot is a lot which does not meet one (1) or more of the minimum dimensional requirements for size or frontage required in the zoning district in which it is located and which is a lot of record the dimensions of which have not been altered since its creation by a voluntary conveyance which rendered such lot more substandard and which was:
  • a) Approved by the Planning Board and duly recorded after August 3, 1959; or
  • b) Approved by the Zoning Board of Review and duly recorded after June 13, 1965; or
  • c) Certified by the Planning Board as "approval not required" and duly recorded after August 3, 1959; or
  • d) Created by a deed or plat duly recorded prior to August 3, 1959.
• 2. Continuance of a use on a substandard lot of record. Any legal use shall be permitted to continue in the manner and extent existing as of the effective date of enactment or amendment of this ordinance, subject to the provisions of this ordinance regarding discontinuance, destruction or demolition, change of use, and extension or alterations.
• 3. Single substandard lots of record.
  • a) A lot or parcel of land having a frontage or lot area that is less than required by Article IV. may be considered buildable for single family residential purposes regardless of the lot frontage or lot area.

    Nothing in this section shall be construed as exempting single family substandard lots of record from complying with the maximum percentage of lot coverage of principal and accessory buildings, maximum height or building setback requirements of Article IV. Any lot meeting those requirements shall be considered as a conforming lot of record for single family residential purposes.

  • b) If a non residential structure can be extended or enlarged in any lawful manner without increasing the extent of its nonconformity, then any extension or enlargement thereof shall only be permitted in such lawful manner upon the granting of a special use permit by the Zoning Board of Review.
• 4. Dimensional variances on substandard lots of record. In appealing for dimensional variances to build a new or enlarge an existing structure on a substandard lot, in addition to the requirements for variances in Article VI. Section D., the Zoning Board of Review shall consider whether such variance:
  • a) Would allow adequate space for fire protection;
  • b) Provide adequate light and air between buildings;
  • c) Would alter the character of the neighborhood, or adversely affect neighboring property;
  • d) Would create lot coverage and setbacks less than the average lot coverage and setbacks of adjacent properties;
  • e) Would impose a substantial detriment to the public or to immediate neighbors.

• 1. A non-conforming use of land lawfully existing at the time of the passage of this Ordinance may be continued provided that such non-conforming use of land shall not in any way be expanded or enlarged, except as provided in this Section.
• 2. A building or structure which is devoted to a non-conforming use existing at the time of the passage of this Ordinance that is lawfully destroyed or involuntarily destroyed, such as by fire or natural catastrophe, shall be completely repaired or completely reconstructed within two (2) years, provided it is devoted to the same use as was made of it before such partial or total destruction, in order to maintain legal non-conforming status.
• 3. When a non-conforming use has been abandoned for more than one (1) year, the building or structure or land that was devoted to such non-conforming use shall not thereafter be returned to such non-conforming use. Abandonment of a nonconforming use shall consist of some overt act, or failure to act, which would lead one to believe that the owner of the nonconforming use neither claims nor retains any interest in continuing the nonconforming use unless the owner can demonstrate an intent not to abandon the use. An involuntary interruption of nonconforming use, such as by fire and natural catastrophe, does not establish the intent to abandon the nonconforming use. However, if any nonconforming use is halted for a period of one (1) year, the owner of the nonconforming use will be presumed to have abandoned the nonconforming use, unless that presumption is rebutted by the presentation of sufficient evidence of intent not to abandon the use.
• 4. A building or structure that exists as a non-conforming use at the time of passage of this Ordinance, may continue to function as a non-conforming use of the same type or any other use that is permitted by this Ordinance, or other such use may be added to the existing use within the confines of the existing building, with the approval of the Zoning Board of Review.

[Amended 6-26-2023 by Ord. No. 2023-06-26B]

• 1.
  • a) With Board of Review approval as a special use permit, a building or structure which is devoted to a non-conforming use which is not a single family residential building or structure, lawfully existing at the time of the passage of this Ordinance may be added to or enlarged provided that the front, side and rear yards, lot coverage, height of such enlarged building or structure and parking requirements meet the zoning requirements of the district in which is located.
  • b) With Board of Review approval as a special use permit, a building or structure which is devoted to a non-conforming use which is a single family residential building or structure, law fully existing at the time of the passage of this Ordinance may be added to or enlarged provided that the front, side and rear yards, lot coverage, height of such enlarged building or structure and parking requirements meet the zoning requirements of the district in which is located or the Board grants dimensional variances in accordance with Section D.
• 2. No lot area shall be so reduced or diminished that the yards or other open spaces or total lot area shall be smaller than prescribed by this Ordinance, unless the reduction in area is due to the taking of a portion of the lot for public use.
• 3. A legally non-conforming use shall not be changed to a use other than a conforming use. The Zoning Board of Review may permit a change in use as a special use permit. Any change in use shall be more in keeping with the characteristics of the neighborhood.
• 4. Any alteration or change in use permitted herein shall adhere more closely to the intents and purposes of this Ordinance.

• 1. An application for relief from the literal requirements of this zoning ordinance because of hardship may be made by an applicant by filing with the Zoning Enforcement Officer an application describing the request and supported by such data and evidence as may be required by the Zoning Board of Review or by the terms of this ordinance. The Zoning Enforcement Officer shall immediately transmit each application received to the Zoning Board of Review and shall transmit a copy of each application to the Planning Board.
  • a) All appeals including appeals involving applications for variances shall be made on forms as provided by the rules of the Zoning Board of Review, and the written ruling or decision of the enforcement official together with all other papers, plans and data constituting the record of the case shall be transmitted to the Zoning Board of Review.
• 2. The Zoning Board of Review, immediately upon receipt of an application for a variance in the application of the literal terms of the zoning ordinance, may request that the Planning Board and/or staff shall report its findings and recommendations, including a statement on the general consistency of the application with the goals and purposes of the comprehensive plan of the Town, in writing to the Zoning Board of Review within thirty (30) days of receipt of the application from that board.
• 3. The Zoning Board of Review shall hold a public hearing on any application for variance in an expeditious manner, after receipt, in proper form, of an application, and shall give public notice pursuant to the provisions of Article XIII.
• 4. A variance shall be defined as: Permission to depart from the literal requirements of a zoning ordinance. An authorization for the construction or maintenance of a building or structure, or for the establishment or maintenance of a use of land, which is prohibited by a zoning ordinance. There shall be only two (2) categories of variance, a use variance or a dimensional variance.
  • a) Use variance. Permission to depart from the use requirements of a zoning ordinance where the applicant for the requested variance has shown by evidence upon the record that the subject land or structure cannot yield any beneficial use if it is to conform to the provisions of the zoning ordinance.
  • b) Dimensional variance. Permission to depart from the dimensional requirements of a zoning ordinance, where the applicant for the requested relief has shown, by evidence upon the record, that there is no other reasonable alternative way to enjoy a legally permitted beneficial use of the subject property unless granted the requested relief from the dimensional regulations. However, the fact that a use may be more profitable or that a structure may be more valuable after the relief is granted shall not be grounds for relief.
• 5. In granting a variance, the Zoning Board of Review shall require that evidence to the satisfaction of the following standards be entered into the record of the proceedings:
  • a) That the hardship from which the applicant seeks relief is due to the unique characteristics of the subject land or structure and not to the general characteristics of the surrounding area; and is not due to a physical or economic disability of the applicant, excepting those physical disabilities addressed in Section 45-24-30(a)(16) General Laws of Rhode Island (amended 2003-04-28);
  • b) That the hardship is not the result of any prior action of the applicant and does not result primarily from the desire of the applicant to realize greater financial gain;
  • c) That the granting of the requested variance will not alter the general character of the surrounding area or impair the intent or purpose of the zoning ordinance or the comprehensive plan upon which the ordinance is based; and
  • d) That the relief to be granted is the least relief necessary.
  • e) That any relief granted is in accordance with the definition of variance provided in this ordinance.
• 6. The Zoning Board of Review shall, in addition to the above standards, require that evidence be entered into the record of the proceedings showing that:
  • a) In granting a use variance the subject land or structure cannot yield any beneficial use if it is required to conform to the provisions of the zoning ordinance. Nonconforming use of neighboring land or structures in the same district and permitted use of lands or structures in an adjacent district shall not be considered in granting a use variance; and
  • b) In granting a dimensional variance, that the hardship suffered by the owner of the subject property if the dimensional variance is not granted amounts to more than a mere inconvenience, (amended 2003-04-28) The fact that a use may be more profitable or that a structure may be more valuable after the relief is granted shall not be grounds for relief.
• 7. Expiration. Any variance which is not utilized within a period of one (1) year from the date of the signing of the decision granting said variance shall be void unless, upon written request of the applicant and good cause shown, the Zoning Board of Review, following a public hearing thereon, grants an extension of not more than one (1) year. Not more than a single, one (1) year extension may be granted following any one (1) public hearing. The Board of Review shall not grant successive extensions which total more than two (2) years on any project, (excluding any extensions granted prior to enactment of this amendment).

    Note: All setbacks above are the same as the base zoning district in which the parcel is located.

  • b) Every lot in a Residential Open Space Development shall have a minimum road frontage of thirty-five feet (35').
  • c) The maximum lot coverage percentage shall be the lesser of the above and the requirements of overlay districts as provided per Article III of this ordinance.
  • d) Any portion of a lot that is less than thirty-five feet (35') in width or depth shall not be counted toward the minimum lot size or setback requirements. This provision shall not apply to corners of lots.
• 6. Development design and layout. The design and layout of a Residential Open Space Development shall follow the provisions of the Land Development and Subdivision Regulations, Article X., Design and Improvement Standards, with the additional requirements set forth in this section. In cases of conflict, the requirements in this section shall supersede the requirements of the Land Development and Subdivision Regulations. The Planning Board shall determine on a case-by-case basis whether the design and layout of a proposed Residential Open Space Development are acceptable according to the provisions herein and per the Land Development and Subdivision Regulations.
  • a) Protection of unique features and sensitive natural areas.

    The lots and dwelling units shall be sized and arranged in a way which maximizes adherence to the Site Design Criteria for Preservation of Unique and Natural Features, Land Development and Subdivision Regulations Article X, Section C, Subparagraph 2. Said subparagraph sets forth criteria by which the Planning Board shall judge whether or not a proposed development will be able "to preserve the natural features of the site, to avoid areas of environmental sensitivity, and to minimize impacts and alteration of natural features, historic and cultural resources, and areas of scenic value which contribute to the Town."

    Residential Open Space Developments will limit housing lots to a smaller portion of the parcel than would a conventional development. They therefore have a greater opportunity to site those lots away from the following sensitive areas:

    • (1) Unique and/or fragile areas, including freshwater wetlands and coastal features;
    • (2) Significant trees or stands of trees, or other vegetative species that are rare to the area or are of particular horticultural or landscape value;
    • (3) Lands in the flood plain, as defined in Article II of the Land Development and Subdivision Regulations;
    • (4) Steep slopes in excess of twenty percent (20%) grade as measured over a ten-foot (10') interval unless appropriate engineering measures concerning slope stability, erosion, and resident safety are taken;
    • (5) Habitats of endangered wildlife, as identified on applicable federal or state lists;
    • (6) Historically significant structures and sites, as listed on federal or state lists of historic places;
    • (7) Agricultural lands;
    • (8) Timber production lands;
    • (9) Vegetated and/or forested buffers protecting sensitive environmental features.
  • b) Perimeter development. In no case shall the minimum distance between any house in a Residential Open Space Development and the nearest lot line of an adjacent parcel outside the subdivision be less than the number of feet required by the zoning setback plus an additional fifty feet (50').
  • c) Street and open space parking requirements.
    • (1) All streets in a Residential Open Space Development which are intended or required for dedication to the Town of Portsmouth shall be improved in accordance with the requirements and specifications contained in the Land Development and Subdivision Regulations.

      Editor's Note: See Ch. 236, Land Development and Subdivision Regulations.

    • (2) Where development design creates streets which are likely never to become through roads, the Planning Board may allow the construction of narrower pavement widths than the minimum of twenty-eight feet (28') established by the Land Development and Subdivision Regulations Article X, Section D, Subparagraph 8. The Planning Board may vary road dimensional requirements from those established by the Land Development and Subdivision Regulations Article X, Section D. All streets within a Residential Open Space Development shall maintain a right-of-way width of no less than fifty feet (50'). Where narrower streets are permitted, the Planning Board may require sidewalks on one (1) or both sides of the street.
    • (3) Common parking spaces on Common Lands, as defined in Section 7, shall not be closer than twenty-five feet (25') from all property lines or street right-of-way lines. The Planning Board may require the provision of landscape materials, screen planting, fences, or other materials designed to provide a buffer between parking areas and adjacent streets or property.

  Editor's Note: See Ch. 236, Land Development and Subdivision Regulations.

• 7. Common lands and open space.
  • a) Definitions.
    • (1) "Common Lands" shall be defined as all land on the parcel that is not included in building lots, paved roadway, and road rights of way. All Common Lands are subject to the provisions herein.
    • (2) "Open Space" shall be defined as that portion of the Common Lands that meets the provisions of Developable Land Area, as defined in Article IV, Section A of this ordinance.
  • b) Minimum open space size requirements.
    • (1) In a Residential Open Space Development, a minimum percentage of the parcel's developable land must be open space. The minimum percentage shall vary by zone, according to the following table:

      	Zone	% of Developable Land which must be Open Space
      	R-20	10%
      	R-30	25%
      	R-40	35%
      	R-60	45%

      • (i) Where a parcel is located in two (2) or more zoning districts, the overall percent open space required shall be based on the percent of the parcel located in each zone. The actual open space provided may be located in one (1) or more of the zones.
    • (2) Total open space in a Residential Open Space Development shall not be less than one (1) acre.
  • c) Open space land qualifications.
    • (1) Undevelopable land, per the definition of "Developable Land Area" in Article IV, Section A of this ordinance, may not count toward the minimum open space size requirement.
    • (2) Land which has been deemed by the Planning Board to be disturbed from its natural state prior to final approval of the development as a result of soil-removal operations, harvesting of trees or other natural features or refuse disposal or other causes shall not count toward the minimum open space size requirement unless and until the land is restored to a condition which the Planning Board determines to be reasonable and appropriate to effect the purposes of this article. The Planning Board may grant final approval for a Residential Open Space Development subject to such restoration of the disturbed land, provided an appropriate performance bond is posted.
    • (3) Areas proposed to fulfill the minimum open space size requirement shall not be excavated or regraded nor shall any disturbance be made to the natural contours of the land nor shall any existing natural vegetation be removed or any natural or man-made features altered in any way except as is needed for recreation or conservation purposes or for drainage facilities as specifically authorized by the Planning Board.
  • d) Size and shape of open space. Open space shall be designed to provide maximum preservation and enhancement of natural areas. To the maximum extent possible, open space shall be preserved in compact shapes, and not as mere extensions of building lots.
    • (1) To the maximum extent reasonably possible, open space parcels shall be contiguous with protected undeveloped land on adjacent parcels, in order to make the open space part of a larger unified open space system.
    • (2) To the maximum extent reasonably possible, open space parcels shall be located so as to be convenient to the dwelling units they are intended to serve. However, because of noise generated by some permitted uses, open space parcels shall be sited with sensitivity to surrounding development.
    • (3) To the maximum extent reasonably possible, each group of house lots in a Residential Open Space Development shall be adjacent and accessible to the open space proportional to the number of houses in the development. (For example, if there are one hundred (100) houses in the development and each of four (4) groups of lots contains twenty-five (25) houses, about twenty-five percent (25%) of the open space shall be adjacent to each group.)
    • (4) A minimal number of narrow strips of not less than twenty-five feet (25') in width of Common Lands shall be permitted only as:
      • (i) Access corridors between residences, streets, and larger Common Lands parcels.
      • (ii) Drainage areas.
      • (iii) Buffers.
    • (5) Reasonable access to open space shall be made readily available to residents of the Residential Open Space Development.
    • (6) The area of each parcel of open space designed for a permitted use or community facility shall be of such minimum size, dimensions, and characteristics as to be functionally usable for that use or facility.
  • e) Permitted common lands uses.
    • (1) Permitted Common Lands uses are chosen because they preserve the land in its current state, which is consistent with the Town's rural character. Only the following uses of the Common Lands shall be permitted, and use thereof shall be limited to the residents of the Residential Open Space Development.
      • (i) Recreation.
      • (ii) Conservation.
      • (iii) Wildlife Management.
      • (iv) Agriculture, as permitted in Article V of this ordinance.
      • (v) Forest Management.
      • (vi) Utility lines, as a special use permit.
      • (vii) Drainage facilities and drainage easements.
    • (2) Common Lands may not be used for commercial or revenue-enhancing purposes, with the exception of agriculture and outdoor golf courses, but not including miniature golf or driving ranges, which may be provided for by permanent easement or long-term lease.
    • (3) Any change of the proposed Common Lands uses must be approved by the Zoning Board of Review as a Special Use Permit.
  • f) Improvements to common lands.
    • (1) As a general principle, Common Lands not developed for community facilities should be left in their natural state.
    • (2) The Planning Board may require a developer to make improvements such as removing dead or diseased trees, planting or thinning of trees or other vegetation, and grading or seeding.
    • (3) The Planning Board may require special provisions for the maintenance of Common Land, private improvements, drainage systems, and utilities, including requirements for security, including a maintenance bond, as provided in Article X of the Land Development and Subdivision Regulations.

      Editor's Note: See Ch. 236, Land Development and Subdivision Regulations.

    • (4) The Planning Board may require the installation of any of the community facilities permitted in Subparagraph g of this section.
    • (5) The Planning Board may allow improvements for agricultural uses, provided that ecologically sensitive land, drainage facilities, and other public improvements remain undisturbed and protected.
  • g) Procedures for approval of community facilities in common lands.
    • (1) Community facilities to be constructed by the applicant shall be submitted as part of the overall Residential Open Space Development plan.
    • (2) The construction of any community facilities subsequent to the approval of a Residential Open Space Development shall be considered as a Special Use Permit and reviewed by the Planning Board per the provisions of Article XI, Development Plan Review, of this ordinance. All community facilities shall be a part of the final submission plans approved by the Planning Board.
    • (3) Subsequent to final plan approval but prior to the conveyance of at least fifty-one percent (51%) of the lots, community facilities may only be permitted after the granting of a Special Use Permit per the provisions of Articles VII and XI of this ordinance.
    • (4) Following the conveyance of at least fifty-one percent (51%) of the lots, community facilities may only be permitted with the permission of the homeowners' association membership and after the granting of a Special Use Permit per the provisions of Articles VII and XI of this ordinance.
  • h) Design criteria for community facilities in common lands.
    • (1) The Planning Board may permit the following types of community facilities to be developed in the Common Lands, consistent with the requirements of this ordinance:
      • (i) Community Structures may include but are not limited to community meeting centers, community art centers, and amphitheaters.
      • (ii) Active Recreational Community Facilities provide recreational or community group opportunities for Residential Open Space Development residents. They may include but are not limited to sports facilities, playgrounds, equestrian centers, pools, beaches, tennis courts, playing fields, and the minimum amount of parking required for these facilities.
      • (iii) Passive Recreational Community Facilities promote human enjoyment of the natural environment. They may include but are not limited to nature parks, nature centers, nature trails, hiking trails, equestrian trails, wildlife observation towers or blinds, and educational displays.
      • (iv) Structures Accessory to Conservation to promote environmental preservation and enhancement. They may include but are not limited to nature preserves, wildlife habitat areas, wildlife nesting platforms or boxes, and wildlife feeders.

      • (vi) Structures Accessory to Golf Courses may include necessary maintenance facilities for use exclusively on the course and a clubhouse, provided it does not serve food or beverage and is used exclusively for golfers.
    • (2) In addition to the criteria for the granting of Special Use Permits as established by Article VII, Section A of this ordinance, the Planning Board shall consider the following:
      • (i) Any community facilities which are permitted in the Common Lands must conserve and enhance the natural features of the Common Lands having regarded their topography and unimproved condition.
      • (ii) Community facilities shall be designed and located so as to be easily accessible and visible from public rights-of-way. All community facilities shall be accessible to the units in the Residential Open Space Development so that all development residents have ready access to, and use of, such facilities.
      • (iii) In total, community facilities which create impervious surfaces shall not exceed twenty percent (20%) coverage of the open space.
      • (iv) Community facilities shall be located at least one hundred feet (100') from the nearest house.
      • (v) Dimensional requirements for community facilities shall be the same as those established by this ordinance for the base zoning district of the Residential Open Space Development.
  • i) Deed restrictions. Any lands dedicated for Common Lands shall contain appropriate covenants and deed restrictions approved by the Planning Board in consultation with the Town Solicitor and duly recorded in the land evidence records, ensuring that:
    • (1) The Common Lands will not be further subdivided or developed in the future;
    • (2) The Common Lands will remain open space;
    • (3) Appropriate provisions will be made for the maintenance of the Common Land; and
    • (4) Common Lands shall not be used for a commercial enterprise, with the exception of agriculture and outdoor golf courses, but not including miniature golf or driving ranges, as provided herein.

The Planning Board shall have the right to approve, modify, or reject the proposed form of ownership if, in its opinion, it does not adequately provide for controls over use and maintenance. As a minimum, the following standards of ownership and management shall be met:
  • a) The Common Lands shall be separate and distinct lot(s) owned in common by all the landowners in the development. The deed to each house lot shall include a fractional interest in the Common Lands in an amount proportional to the number of house lots in the development. The deed shall also include all covenants, restrictions, or easements which shall be imposed upon the use, management, or maintenance of the Common Lands in order to provide for the necessary control and requisite upkeep of the Common Lands, including requirements for liability insurance.
  • b) The developer shall provide for and establish a homeowners' association which shall be responsible for the use, care, and maintenance of all Common Lands and any improvements thereon. Unless otherwise allowed by the Planning Board, membership in the homeowners' association shall be mandatory for all landowners within the Residential Open Space Development.

• 1. Purpose.

  	The purpose of this section is to provide a procedure for the evaluation and approval of integrated developments focused on planned employment uses, including industrial, light industrial, office and research and development uses, retail/service developments, marina and resort-style development, and addressing the particular needs of marine trade uses. [Amended 10-27-2004 ; 2-4-2008 ]
  	The regulations are intended to foster developments which are compatible with surrounding areas and which incorporate buffers or transition areas to reduce potential negative impacts on single family residential areas. The regulations are intended to encourage a mixture of compatible uses to create a sustainable and attractive environment for a wide variety of trades and businesses. The regulations are intended to be flexible, to allow for innovative design techniques, accommodate unique land uses and encourage creative approaches to development issues.
  	A coordinated design approach with an emphasis on compatibility with the natural environment and surrounding land uses and the allowance of a sufficient mix of uses and accessory uses to create a self-contained or self-sustained development park is encouraged. Planning of a project and calculation of densities over the entire project rather than on an individual lot-by-lot basis is permitted. A coordinated design approach should: [Amended 2-4-2008 ]
  		•	Break up the apparent mass and scale of large structures, as well as large paved areas, in order to ensure that such development is compatible with and does not detract from Portsmouth's character, scale, and sense of place;
  		•	Help integrate large-scale development with its surroundings;
  		•	Promote and facilitate a safe and comfortable pedestrian scale environment;
  		•	Encourage a mixture of uses and sizes of structures; and
  		•	Reduce the visual impact of large areas of parking.
  	The regulations are intended to be flexible, to allow for innovative design techniques, accommodate unique land uses and encourage creative approaches to development issues. It is anticipated that public officials will have considerable involvement in determining the nature of the development through the development plan review process which will include consideration and application of aspects of both subdivision and zoning regulations. [Added 2-4-2008 ]
  	Where the requirements of any part of this section may conflict with any other section, this section shall prevail. [Added 2-4-2008 ]

    • (1) The Land Development and Subdivision Regulations of the Town of Portsmouth for Major Land Development and Major Subdivision Review.

      Editor's Note: See Ch. 236, Land Development and Subdivision Regulations.

    • (2) Additional procedures and requirements set forth herein for Planned Unit Developments.
  • c) Compatibility and interrelation of uses within the Planned Unit Development and coordination of traffic, utilities, parking, storm water management, security, sewage disposal, storage, open space, infrastructure and other needs, as well as the entire development's impact on the surrounding area and roadways mandates that the development be considered in its entirety and approved, if appropriate, as a whole and developed as a whole. Phasing of construction may be permitted or required by the Planning Board.
  • d) In granting a planned unit development under this section the Planning Board shall, immediately upon receipt of an application hereunder, refer the site plan and related documents to the Design Review Board, as well as to the Portsmouth Redevelopment Agency for proposals in the Redevelopment District, for review and advice, per the stipulations of Article XI. Development Plan Review. The Redevelopment District Performance Standards shall be used to help evaluate proposals in the Redevelopment District.

    [Amended 2-4-2008; 3-15-2010]

  • e) "Performance Standards for Planned Unit Developments", adopted by the Planning Board, hereinafter referred to as "Performance Standards", shall be utilized, as applicable, for evaluating Planned Unit Development proposals. The Redevelopment District Performance Standards shall be used to help evaluate proposals in the Redevelopment District.

    [Amended 9-19-2006]

• 3. Minimum land area.
  • a) A Planned Unit Development shall consist of not less than two hundred thousand square feet (200,000 ft.²), except Planned Retail/Service Developments which shall consist of not less than one hundred thousand square feet (100,000 ft.²) or eighty thousand square feet (80,000 ft.²) in the Town Center District, or twenty (20) acres in the Redevelopment District of developable land area which may be subdivided into lots as set forth in section 6 hereof.

  • b) Once a planned unit development has been approved, all land area shown on the plan submitted as part of said development, including those designated as reserved for future development, shall be dedicated to the development and may not be withdrawn from said development plan or devoted to any other use without the express consent of the Planning Board. The Board may allow subsequent withdrawal of land from a development, after hearing, when such withdrawal will not violate the purpose and intent of this ordinance, impair the previously approved plan of coordinated development or deprive the public or the development of benefits or amenities in exchange for the provision of which the applicant was previously granted zoning incentives or modifications.
• 4. Uses.
  • a) Uses - generally.

    [Added 9-19-2006]

    • (1) Uses are categorized as "permitted", "conditional", and "prohibited". (Consideration of "conditional" is similar to that for special use permits in zoning, but adds a requirement that the use fit the intent of the particular PUD.)
    • (2) Designation as a conditional use does not constitute an authorization or an assurance that such use will be permitted. Rather, each application for a conditional use shall be evaluated as to its internal consistency with the intent of the proposed PUD, its probable effect on the intent of said development, the adjacent property, the neighborhood, and on the community and may be approved or denied as the findings indicate appropriate.
    • (3) Nothing herein contained shall preclude the Planning Board from granting multiple conditional uses for a proposal or to condition the granting of one (1) or more conditional uses upon the implementation or completion of one portion of a project, a master plan for which is submitted at the time of the application for a planned unit development.

      • (iv) Standards of design and construction for roadways, either public or private, within a planned unit development may be modified as deemed appropriate by the Planning Board, (including the reduction of right of way and roadway widths). In considering an application to modify standards the Board shall take into consideration the particular natural characteristics of each site, the existence of other design factors such as the separation of pedestrian and vehicular circulation patterns and the location and adequacy of off-street parking and loading facilities and the impact of any modification on circulation, safety, maintenance, storm water drainage. The Board shall consult with the Fire Department, Police Department, and Public Works Department, and if, after such consultation, the Planning Board finds that the design of the proposed streets and common vehicular ways is adequate to protect the public health, safety and welfare and will promote the purposes and intent of this ordinance, the Board may modify such standards.
      • (v) Private streets and ways may only be approved upon the submission of instruments granting the appropriate occupants of the development and state and municipal government and regulatory agencies satisfactory access over and across said streets and ways and setting forth the responsibilities of the occupants or owners of the development or development association or management committee, if any, regarding maintenance, repair and control of said streets and ways and the arrangements for financing same, and setting forth the rights of public and private utilities and the Town of Portsmouth.

  • c) Site design criteria.
    • (1) Generally - arrangement of buildings should provide more economy of roads and internal parking than normally associated with conventional development. Buildings and structures shall be located with consideration given to the topography of the development and shall be adapted to the terrain, the size and shape of the lot, the character of adjoining properties and existing structures in the immediate vicinity which have a visual relationship with the development. Environmentally sensitive areas shall be avoided and neighboring properties shall be buffered from objectionable features. Factors such as drainage, noise, odor, and the character of surrounding properties shall be considered in location of buildings and structures. All buildings shall be set back a minimum of fifty-five feet (55') from the centerline of any interior way, provided that such restriction shall not apply to PMTD or PRSD (amended 2003-07-14) and building in those developments shall be set back from the centerline such distance as the Planning Board may determine is necessary and prudent for installation and access to utilities and the maintenance of safe vehicular and pedestrian traffic patterns, taking into consideration the nature of the interior way and surrounding buildings and improvements. In no case may the minimum distance between any principal building in a PUD and the nearest lot line of an adjacent parcel outside the PUD and located in a residential district, be less than the rear yard setback required in the respective, adjacent residential district. The Board may not grant modifications or waivers of this requirement.
    • (2) Nothing in this ordinance shall be construed to prevent or discourage the erection or maintenance of two (2) or more buildings on any one (1) lot in a planned unit development, notwithstanding the fact that both of said buildings are of such character, size or use that they would otherwise be characterized as "principal buildings" under other provisions of this ordinance.
    • (3) To the extent reasonably possible, structures within the development shall be compatible in architectural characteristics such as proportion, scale, roofline, general style, patterns, and proportion of windows and architectural details and features.
    • (4) Building materials shall be compatible to neighboring sites and structures. A finished texture, pattern, or a quality of detailing shall be depicted on plans for all proposed building materials.
    • (5) Uses and structures shall be dispersed throughout the development so that the uses which are least intensive in terms of noise, traffic, odor, hours of operation, etc., and those uses that by their nature may be conducted in structures that are more architecturally compatible with surrounding properties shall be located on the perimeter of the development. Those uses which are most intensive in terms of noise, smoke, odor, vibration or traffic or possess other potentially objectionable features and those uses which by their nature require buildings, and structures of a more standard industrial design, shall be confined to the interior of the development or to an area of the development abutting similar uses on abutting properties.
    • (6) The Board may require the reservation or dedication of easements for the benefit of land reserved for future development or land outside the development to allow those parcels to enjoy access to waterways, rail lines, highways, utility lines and facilities where such reservation or dedication is reasonably necessary to allow the coordinated, efficient and beneficial development and use of such properties and does not severely impair the value of the development or hinder the development or use of the subject parcel. Reservation or dedication of such areas may be cause for grant of modification or incentives pursuant to section 8 hereof.
    • (7) Parking in the front yard or in view of properties outside the development shall be discouraged and may be denied. Consolidated curb cuts for access to the development or to secondary roads within the development are encouraged and may be required by the Board.
    • (8) In a Planned Corporate Development and Planned Retail/Service Development (amended 2003-07-14) all areas not covered by buildings/structures, parking, and travel, areas shall be landscaped with grass, trees, shrubs, flowers, or ground cover indigenous to the area. Along the length of the front wall of each principal building there shall be a landscaped area with bushes, shrubs, or flowers indigenous to the area.
    • (9) Any outdoor storage allowed in a Planned Corporate Development and Planned Retail/Service Development (amended 2003-07-14) shall be screened from view by an opaque screen architecturally compatible with the principal structure. After consideration of factors such as the use, topography, natural or proposed vegetation and the nature of surrounding property, the Board may require such screening in any Planned Unit Development.
    • (10) In any PID, PCD, or PRSD not in the Town Center District, where any facade of any building over twenty-five thousand SF (25,000 ft.²) faces any adjacent residential parcel within one hundred feet (100'), a permanent berm containing at a minimum evergreen trees or arborvitae at least six feet (6') in height when planted, planted at intervals of twenty feet (20') on center. Height and width or berm as well as type and locations of plantings shall be designed by a registered landscape architect or certified arborist, and shall be designed to create an effective visual screen from said residential use. Depending upon the size and nature of the development, the Board may require up to a double row of six foot (6') high evergreen trees planted at minimum intervals of ten feet (10') on center or in clusters or clumps shall be provided. Existing trees and shrubbery, or other suitable visual barrier, may substitute for this requirement, at the discretion of the Board.

      [Added 2-4-2008]

    • (11) Planned Retail/Service Developments shall adhere to the requirements of Article VII. Section G. Planned Retail/Service Development. In case of conflict, this section shall prevail, but in no case shall the standards herein be less stringent than that section.

      [Added 2-4-2008]

  • d) Traffic impact. Subparagraph d) is applicable to PRSD only.

    [Added 2-4-2008]

    • (1) The principal vehicular access to the site shall be directly from an arterial street. The Board may waive this requirement if there is no reasonable alternative or it is deemed advantageous to the Town, and a traffic impact study demonstrates that the Level of Service on collector road or residential street(s) serving as the principal access will not be reduced below level C weekdays 7-9 AM or 4-6 PM, or Saturdays noon to 5:00 PM.
    • (2) Vehicle access shall be designed to accommodate peak on-site traffic volumes to minimize traffic impact on public streets and maximize pedestrian safety. This shall be accomplished through adequate parking lot design and capacity; access drive entry throat length, width, design, location, and number; and traffic control devices.
    • (3) The site design shall provide, or make provisions for, direct connections to adjacent land uses in locations used or likely to be used for parking unless expressly waived by the Board.
    • (4) For proposed retail developments with greater than twenty-five thousand SF (25,000 ft.²) of gross floor area of the first floor, the Board may, at its option and at the expense of the applicant, employ a transportation planner or transportation engineer to determine the traffic impact of the proposed development through a traffic impact analysis using the Institute of Transportation Engineers' trip generation guidelines. In no instance may a proposed development reduce 1) the existing Level of Service on the adjacent arterial road, or 2) below Level C on the nearest non-arterial through streets weekdays 7-9 AM or 4-6 PM, or Saturdays noon to 5:00 PM.
• 7. Inspections and construction or improvement guarantees. The provisions of Sections N, O, P, and Q of Article X of the Land Development and Subdivision Regulations of the Town of Portsmouth shall be applicable to all improvements for which the Town will ultimately assume the responsibility for maintenance or operation including, but not limited to, public roads and drainage facilities. The Planning Board, in its judgment, may require inspections and approvals and impose the fees associated therewith, pursuant to Sections N, O and Q of Article X, for any private improvement which could detrimentally impact the operation or useful life of any public improvements, if not properly installed or maintained.

  Editor's Note: See Ch. 236, Land Development and Subdivision Regulations.

• 8. Incentives and modifications. In addition to the modifications allowed pursuant to Section 6.a) hereof the Board shall further be empowered to modify or vary any provisions hereof upon a finding that such variance or modification will be conducive to an integrated development, will not be inimical to public health, safety and welfare, and that the applicant is establishing an amenity or feature of significant value to the Town and/or general public, such as, but not limited to, public open space, public recreational facilities, access to the coastline, accommodation for mass transportation, or the like.
• 9. Ownership and control. Prior to approval, the applicant must designate an entity, whether a management or condominium association, fee simple owner, partnership, corporation or other entity which will have direct control and responsibility for the installation and maintenance of all common areas such as parking facilities, private roadways, open space, buffer strips, and utilities, joint storm water and/or wastewater facilities and public facilities. Applicant must submit for approval documents which govern the existence and operation of such entity, vest management rights in such entity and set forth the procedure, if any, for substitution of any party for such entity.
• 10. Changes to plan.
  • a) Proposed changes to an approved PUD shall be considered in accordance with Portsmouth Subdivision Regulations Article XIII. Section G.

    Editor's Note: See Ch. 236, Land Development and Subdivision Regulations.

  • b) In addition, the basis for acceptance of a proposed change shall include a finding that the public benefits and mitigation provided improves or remains equal to those originally approved, and that the change in the approved building and development program is sustainable and retains the character of the original concept. The Planning Board shall have the authority to declare that proposed changes, taken as a whole, are a significant departure from the original approval and constitute a new proposal.
• 11. Procedure and decision.

  The Planning Board shall conduct public hearings on the application in accordance with the procedures established by the Portsmouth Land Development and Subdivision Regulations for Major Land Development and Major Subdivision Review regardless of whether the project constitutes a subdivision. The Board may require a personal inspection of the site by some or all Board members as a condition of Master Plan approval or at any time prior to final approval. During the course of said hearings the Board may require the applicant to produce, at applicant's sole cost and expense, such further information, plans, studies or data not specifically required by this ordinance or the Board's regulations if the Board deems such information or data is reasonably necessary to enable the Board to make the determinations with which it is charged hereunder. In the event the Board determines that independent, professional expertise is necessary to ensure proper and thorough investigation of the project or interpretation of data, plans, information or studies provided by applicant that the Board may engage the services of such expert.

  The Planning Board, may, at its discretion, establish a Technical Review Committee to conduct technical reviews of specific applications subject to their jurisdiction on an as-needed basis. This committee shall operate per the provisions of the Subdivision Regulations, Article XII, Section B.

  [Added 9-19-2006]

  At the conclusion of said hearings, the Board may approve said application, deny the application, approve the application in part and deny the application in part or approve it with modifications and/or subject to conditions and restrictions. In the course of granting any approval, the Board shall have the power to restrict or limit the potential uses of land within the development which the application designates as reserved for future development.

  The Board shall approve a planned unit development as defined herein if, after the review provided for herein, it finds:

  • a) That the development promotes the efficient use of land by providing a well coordinated and integrated development arrangement capable of accommodating varied but compatible land uses within the development and does not create any lot unsuitable for development except those reserved or dedicated to open space.
  • b) That any adverse impacts to surrounding properties shall be mitigated by use of appropriate design techniques, open space, screening, etc.
  • c) That the development as proposed complies with the standards and provisions of the zoning ordinance, except as the same are specifically modified by the Board.
  • d) That there will be no significant, negative environmental impacts from the proposed development as shown on the plan with all conditions for approval.
  • e) That the proposed development and its location are consistent with the Portsmouth Comprehensive Community Plan.

  Editor's Note: See Ch. 236, Land Development and Subdivision Regulations.

    • (1) Up to seventy-five percent (75%) of the parking spaces required for theaters, public auditoriums, banquet facilities, and church auditoriums may be provided and used jointly by offices, retail, service establishments, schools, and similar uses not normally open, used, or operated during the same hours as those uses listed above.
    • (2) Up to thirty percent (30%) of the parking spaces required for the predominant use on a site may be shared with other uses operating during the same time of day and days of the week. The predominant use is considered to be that which requires the most parking of those sharing the parking facilities.

      [Amended 2-4-2008]

• 9. Off-street loading requirements.
  • a) Adequate off-street loading shall be provided for each use. Loading bays shall be located at the side or rear of the building they are intended to serve. Off-street loading facilities required by this section shall be maintained as long as the building, use or structure remains.

Parking lots containing fifteen (15) or more spaces shall be planted with at least one (1) tree per twelve (12) spaces, no smaller than two-inch (2") caliper (trunk diameter at four-foot (4') height), each tree being surrounded by no less than fifty square feet (50 ft.²) of permeable, unpaved area.
    • (1) All landscaping shall be contained in planting beds. Each planting bed shall have a minimum area of fifty square feet (50 ft.²) and shall be enclosed by appropriate curbing or similar device at least six inches (6") wide and six inches (6") in height above the paving surface. Planting beds may be located below the grade of the paved lot in order to absorb some surface water runoff.
    • (2) Interior landscaping features shall be arranged in a linear manner in order to provide a consistent pattern of parking. On each end of a landscaped feature shall be planted either a tree with a minimum vertical clearance of branches six feet (6') from the ground or one (1) or more shrubs not less than two feet (2') in height nor more than four feet (4') in height.
    • (3) Interior landscaping features containing trees shall be contained in peninsulas or islands having a minimum width of eight feet (8') and a minimum length of eighteen feet (18'). There shall be a minimum of four feet (4') to the center of all trees from the edge of paving where vehicles overhang.
    • (4) Grass, ground cover or mulch with a growth-preventing pervious underlayment shall be planted on all portions of the landscape area not occupied by other landscape material.
    • (5) In order to provide that the required landscape areas be properly dispersed, no required landscape area shall be larger than the following:
      • (i) Three hundred fifty square feet (350 ft.²) in parking areas under thirty thousand square feet (30,000 ft.²).
      • (ii) One thousand five hundred square feet (1,500 ft.²) in parking areas over thirty thousand square feet (30,000 ft.²).
      • (iii) Landscape areas larger than the above are permitted as long as the additional area is in excess of the required minimum.
    • (6) All landscaped islands shall be situated below the grade of the parking spaces and driving aisles such that stormwater runoff flow is directed to and trapped by such islands.

      [Added 2-4-2008]

  • f) Perimeter buffer and screening. The intent of perimeter buffers and screening is to minimize, to the greatest extent practicable, visual and noise impacts on abutting residential properties from buildings, parking lots, and accessory uses and equipment (lighting, loading, traffic, etc.). For parking lots over one hundred (100) spaces, the intent is to screen such items from view from adjacent residential properties, to the greatest extent practicable, and from the street, while still allowing sufficient visibility for the intended use of the property.

    Perimeter buffer and screening should be minimized for developments within the Town Center Zoning District, except within rear setbacks that abut residential zones.

    [Added 2-4-2008]

    • (1) Parking areas must be screened along lot lines bordering institutional or residential uses or residential zones and along street frontages. A landscaped buffer area at least twenty feet (20') wide to the rear lot line and ten feet (10') wide to the side lot lines is required. The front landscaped buffer along a public street shall be the depth of the required front yard or twenty feet (20'), whichever is less. For parking lots over one hundred (100) spaces, the Zoning Board of Review or Planning Board, as applicable, may require a landscaped buffer up to fifty feet (50') wide. Such width shall be based upon:

      [Amended 2-4-2008]

      	•	Size and intensity of proposed use;
      	•	Relative topography of the proposed development to adjacent residential development;
      	•	Placement of parking, loading and service areas;
      	•	Landscaped and/or solid screening.

    • (2) All trees shall be a minimum of two-inch (2") caliper (trunk diameter) when planted. Native trees and shrubs shall be planted wherever possible, in order to capture the "spirit of the locale" through indigenous species. Trees shall be of a type that will survive urban conditions with little or no maintenance.
    • (3) For parking lots over one hundred (100) spaces, up to seventy-five percent (75%) of the lot frontage adjacent to any arterial street, not including vehicular and pedestrian entrances, may be required to include screening of on-site parking by means of on-site buildings, which may include the primary structure, as well as dense landscaping, or a combination.

      [Added 2-4-2008]

    • (4) For parking lots over one hundred (100) spaces, seventy-five percent (75%) of the lot frontage adjacent to all other streets shall provide screening of on-site parking.

      [Added 2-4-2008]

    • (5) Lot frontage adjacent to residential use or residential zoning districts shall provide screening of on-site parking by means of walls, landscaping, landscaped berms, or buildings.

      [Added 2-4-2008]

    • (6) Upon variance, a landscaped buffer of not less than at least six feet (6') wide, may be permitted provided it is densely planted with a mixture of deciduous and evergreen trees and shrubs to create an effective visual barrier.
    • (7) Any fire lane and setback of the fire lane from a building required by the Portsmouth Fire Department may not count toward the landscaped buffer requirement.

      [Added 2-4-2008]

    • (8) Maintenance of significant trees.

      [Added 2-4-2008]

      • (i) Removal of viable live trees greater than twelve inches (12") in caliper is expressly prohibited within any required landscaped buffer, except invasive species that tend to choke out other growth. An area of six feet (6') on all sides of such trees may not be paved.
      • (ii) Removal of viable live trees greater than twelve inches (12") in caliper within the proposed building footprint or within the parking area may be approved by the Board if no reasonable alternative is available.
      • (iii) A tree deemed "destroyed" by a certified arborist chosen by the Town at the applicant's expense may be removed with the approval of the Zoning Enforcement Officer.
  • g) Screening material.

    [Added 2-4-2008]

    • (1) Suitable temporary visual screening at least six feet (6') in height shall be installed within any required buffer prior to the commencement of any other construction, excavation, land clearing or grading activities.
    • (2) Where any parking lot or section of a parking lot greater than one hundred (100) spaces faces residential uses on adjacent lots within one hundred feet (100'), a permanent berm containing at a minimum evergreen trees or arborvitae at least six feet (6') in height when planted, planted at intervals of twenty feet (20') on center. Height and width or berm and locations of plantings shall be designed by a registered landscape architect or certified arborist to meet the intent of this section. Depending upon the size and nature of the development, the appropriate Board may require up to a double row of six foot (6') high evergreen trees planted at minimum intervals of ten feet (10') on center or in clusters or clumps shall be provided. Existing trees and shrubbery, or other suitable visual barrier, may substitute for this requirement, at the discretion of said Board. At its option, said Board may require a solid wood fence of six feet (6') in height in addition to or in place of said berm, but not in place of the evergreen trees or arborvitae. Wood fences on the perimeter of a lot shall be installed with the finish side of the fence slats facing toward the neighboring property.
    • (3) Chain link or wire mesh fence may not be used as a screening material.
  • h) Landscaping for service structures.
    • (1) In all non-industrial zones, outdoor storage areas, exposed machinery, service structures including propane tanks, dumpsters and outdoor areas used for the storage and collection of rubbish, air conditioning units and condensers, electrical transformers, and other equipment or elements providing service to a building or a site must be visually screened from roads and surrounding land uses. Suitable types of screening include opaque wood fences and dense evergreen hedges of five feet (5') or more in height. Service structures in an industrial zone shall be fully screened when located within thirty-five feet (35') of any zone other than industrial.
    • (2) A continuous planting, hedge, fence, wall, or earth mound shall enclose any service structure on all sides unless such structure must be frequently moved, in which case screening on all but one (1) side is required. The average height of the screening material shall be one foot (1') more than the height of the enclosed structure, but shall not be required to exceed eight feet (8') in height. If service structures are screened by plant material, such material may count towards the fulfillment of perimeter landscaping. In locations where potential health or safety hazards may arise (such as rubbish storage/collection areas), a solid wooden fence, six feet (6') in height is required (to deter children and animals from entering the premises).
  • i) Vision clearance. All developments, signs, landscaping and other improvements shall provide for clear, unobstructed vision for pedestrians and motorists entering, exiting or moving within any development.
    • (1) Pertaining to street intersections, entrances or exits from parking lots, and intersections of parking lot aisles and driveways, there shall be a three (3)-dimensional area between the height of three feet (3') and seven feet (7') from the ground for a distance of thirty feet (30') from the corner in which nothing exists, is erected, placed, planted or allowed to grow in such manner as to materially impede vision.

[Amended 8-15-1994; 4-13-2026 by Ord. No. 2026-04-13B]

• 1. Purpose, intent and interpretation.
  • a) The intent of this section is to provide comprehensive and balanced sign regulations that will protect the health, safety and general welfare of the community; preserve the right of free speech and expression; avoid excessive levels of visual clutter or distraction that are potentially harmful to traffic and pedestrian safety, property values, business opportunities, and community appearance; and ensure that signs are well-constructed and maintained and expressive of the identity of individual activities and the community as a whole. This section's purpose is to allow adequate communication through signage while encouraging aesthetic quality in the size, type, location and purpose of all signs. This section must be interpreted in a manner consistent with the First Amendment guarantee of free speech.
  • b) All regulations in this section apply without regard to the content, viewpoint, or message expressed on any sign. The Town shall not review, approve, or deny a sign based on the communicative content displayed, except to the limited extent permitted by the United States or Rhode Island Constitutions.
• 2. Severability.
  • a) If any part, subsection, paragraph, subparagraph, sentence, phrase, clause, term, or word in this section of the zoning ordinance is found by a court of competent jurisdiction to be invalid, such invalidity shall not affect the validity or enforceability of the remaining portions of this section of the Ordinance.
• 3. Noncommercial signs.
  • a) Any sign authorized by this Ordinance may contain a noncommercial message. Non-commercial signs shall be subject to the same permit requirements, restrictions on size and type, and other specifications set forth in this section.
  • b) Copy substitution. The owner of any lawfully installed sign may change, replace, or substitute the graphic, text, logo, color, or other copy displayed—whether commercial or non-commercial—without additional approval, permit, or fee, so long as:
    • (1) The alteration does not increase the sign's area or height;
    • (2) The supporting structure, lighting type, and location remain unchanged; and
    • (3) A non-illuminated sign is not converted to an illuminated sign.

  • d) Appeals.
    • (1) Decisions of the ZEO under this Article (including NOVs, permit denials, and reclassification of temporary signs) may be appealed to the Zoning Board of Review in accordance with R.I.G.L. § 45-24-57.
    • (2) Filing an appeal within the cure period stays enforcement actions — except for immediate hazards — until the Board issues a decision.

  • f) Amortization of existing non-conforming signs.
    • (1) Any permanent sign that was lawful on the effective date of this ordinance but does not conform to the new dimensional, height, lighting, or location standards shall be removed or brought into full compliance within three (3) years of the adoption date of this Article, unless a shorter period is imposed as a condition of a permit or approval. The Zoning Board of Review may grant an extension of up to one (1) additional year upon a showing of substantial hardship that is not self-created.
• 17. Applicability in overlay districts.
  • a) Where properties are located within a development subject to design review and designated as such in Article VII of the Portsmouth Zoning Ordinance (or any other overlay district with separate sign or architectural guidelines) such properties and any signage located within those properties will be governed by the Portsmouth Design Review Guidelines. Where an overlay district provides for its own separate sign or architectural guidelines the more restrictive standard shall govern.
  • b) Compliance with this ordinance does not relieve any applicant from also complying with any other applicable provisions of the Zoning Ordinance, or design overlay standards. All sign applications in such districts must be reviewed in accordance with those additional requirements.

• 2. The complaint shall set forth with specificity the area or areas in which the enactment or amendment does not conform with the comprehensive plan and/or the manner in which it constitutes a taking of private property without just compensation.
• 3. The court shall first consider whether the enactment or amendment of the zoning ordinance is in conformance with the comprehensive plan. If the enactment or amendment is not in conformance with the comprehensive plan, then the court shall invalidate the enactment or the amendment, or those parts of the enactment or amendment which are not in conformance with the comprehensive plan. The court shall not revise the ordinance to conform with the comprehensive plan, but may suggest appropriate language as part of the court decision.
• 4. In the case of an aggrieved party, where the court has found that the enactment or amendment of the zoning ordinance is in conformance with the comprehensive plan, then the court shall next determine whether the enactment or amendment works as a taking of property from the aggrieved party. If the court determines that there has been a taking, the court shall remand the case to the legislative body of the Town, with its findings that a taking has occurred, and order the Town to either provide just compensation or rescind the enactment or amendment within thirty (30) days.
• 5. The Superior Court shall retain jurisdiction, in the event that the aggrieved party and the Town do not agree on the amount of compensation, in which case the Superior Court shall hold further hearings to determine and to award compensation. Furthermore, the Superior Court shall retain jurisdiction to determine the amount of an award of compensation for any temporary taking, if that taking shall exist.
• 6. The court may, in its discretion, upon motion of the parties or on its own motion, award reasonable attorney's fees to any party to an appeal, as set forth herein, including a town.

In accordance with Title 45, Chapter 53 of the Rhode Island General Laws, the Low and Moderate Income Housing Act, the Portsmouth Planning Board is designated as the local review board, and shall have the power to issue a comprehensive permit for a qualifying low and moderate income housing project.

Any applicant proposing to build low or moderate income housing may submit to the Planning Board a single application for a comprehensive permit to build that housing in lieu of separate applications to the applicable local boards. This procedure is only available for proposals in which at least twenty-five percent (25%) of the housing is low or moderate income housing. The application and review process for a comprehensive permit shall be as follows:

• 1. Submission requirements. Applications for a comprehensive permit shall be submitted to the Administrative Officer of the Planning Board and shall include:
  • a) A letter of eligibility issued by the Rhode Island Housing Mortgage Finance Corporation, or in the case of projects primarily funded by the U.S. Department of Housing and Urban Development or other state or federal agencies, an award letter indicating the subsidy, or application in such form as may be prescribed by the Town of Portsmouth for a municipal government subsidy; and
  • b) A written request to the Planning Board to submit a single application to build or rehabilitate low or moderate income housing in lieu of separate applications to the applicable local boards. The written request shall identify the specific sections and provisions of applicable local ordinances and regulations from which the applicant is seeking relief; and
  • c) A proposed timetable for the commencement of construction and completion of the project; and
  • d) A sample land lease or deed restriction with affordability liens that will restrict use as low and moderate income housing in conformance with the guidelines of the agency providing the subsidy for the low and moderate income housing, but for a period of not less than thirty (30) years; and
  • e) Identification of an approved entity that will monitor the long-term affordability of the low and moderate income units; and
  • f) A reasonably detailed financial pro-forma, or a copy of the financial pro-forma provided to the RI Housing and Mortgage Finance Corp., for the proposed development; and
  • g) For comprehensive permit applications:
    • (1) Not involving major land developments or major subdivisions including, but not limited to, applications seeking relief from specific provisions of the zoning ordinance, or involving administrative subdivisions, minor land developments or minor subdivisions, or other local ordinances and regulations: those items required by local regulations promulgated pursuant to applicable state law, with the exception of evidence of state or federal permits; and for comprehensive permit applications; and
    • (2) Involving major land development projects and major subdivisions, unless otherwise agreed to by the applicant and the Town; those items included in the master plan checklist for low or moderate income housing as provided in the Town of Portsmouth Land Development and Subdivision Regulations promulgated pursuant to § 45-23-40 of the Rhode Island General Laws. Subsequent to master plan approval, the applicant must submit those items included in the preliminary plan checklist for low or moderate income housing for a major land development project or major subdivision as provided in the Land Development and Subdivision Regulations promulgated pursuant to § 45-23-41, with the exception of evidence of state or federal permits.

      Editor's Note: See Ch. 236, Land Development and Subdivision Regulations.

    • (3) All required state and federal permits must be obtained prior to the final plan approval or the issuance of a building permit. Such final plan submission shall include written evidence that the Plans approved at the master plan or preliminary stages have not materially changed.
  • h) The Town may impose fees on comprehensive permit applications that are consistent with but do not exceed fees that would otherwise be assessed for a project of the same scope and type but not proceeding as a comprehensive permit application, provided, however, that the imposition of such fees shall not preclude a showing by a non-profit applicant that the fees make the project financially infeasible; and
  • i) Notwithstanding the submission requirements set forth above, the Planning Board may request additional, reasonable documentation throughout the public hearing, including, but not limited to, opinions of experts, credible evidence of application for necessary federal and/or state permits and/or financial assistance, statements and advice from other local boards and officials.
• 2. Certification of completeness. The application must be certified complete or incomplete by the Administrative Officer according to the provisions of the Land Development and Subdivision Regulations provided, however, that for a major land development or major subdivision, the certificate for a master plan shall be granted within thirty (30) days and for a preliminary plan shall be granted within forty-five (45) days. The running of the time period set forth herein will be deemed stopped upon the issuance of a certificate of incompleteness of the application by the Administrative Officer and will recommence upon the resubmission of a corrected application by the applicant. However, in no event will the Administrative Officer be required to certify a corrected submission as complete or incomplete less than fourteen (14) days after its resubmission. If the Administrative Officer certifies the application as incomplete, the officer shall set forth in writing with specificity the missing or incomplete items.
• 3. Pre-application conference. Where the comprehensive permit application proposal is a major land development project or a major subdivision pursuant to the Land Development and Subdivision Regulations the Planning Board may require an applicant proposing a project under this section to first schedule a pre-application conference with the Planning Board, the Technical Review Committee established pursuant to the Land Development and Subdivision Regulations, or with the Administrative Officer for the Planning Board and other local officials, as appropriate. To request a pre-application conference, the applicant shall submit a short description of the project in writing including the number of units, type of housing, as well as a location map. The purpose of the pre-application conference shall be to review a concept plan of the proposed development. Upon receipt of a request by an applicant for a pre-application conference, the Town has thirty (30) days to schedule and hold the pre-application conference. If thirty (30) days have elapsed from the filing of the pre-application submission and no pre-application conference has taken place, nothing shall be deemed to preclude an applicant from thereafter filing and proceeding with an application for a comprehensive permit.

  Editor's Note: See Ch. 236, Land Development and Subdivision Regulations.

• 4. Review of applications. An application filed in accordance with this section shall be reviewed by the Planning Board at a public hearing in accordance with the following provisions:
  • a) Notification. Upon issuance of a certificate of completeness for a comprehensive permit, the Planning Board shall immediately notify each local board, as applicable, of the filing of the application, by sending a copy to the local boards and to other parties entitled to notice of hearings on applications under the zoning ordinance and/or Land Development and Subdivision Regulations as applicable.
  • b) Public notice. Public notice for all public hearings will be the same notice required under the Land Development and Subdivision Regulations for a public hearing for a preliminary plan promulgated in accordance with Article VI, Section E thereof. The cost of notice shall be paid by the applicant.
  • c) Review of minor projects. The review of a comprehensive permit application involving only minor land developments or minor subdivisions or requesting zoning ordinance relief or relief from other local regulations or ordinances not otherwise addressed in this subsection, shall be conducted following the procedures in the Land Development and Subdivision Regulations, with the exception that all minor land developments or minor subdivisions under this section are required to hold a public hearing on the application, and within ninety-five (95) days of issuance of the certificate of completeness, or within such further time as is agreed to by the applicant and the Planning Board, render a decision.
  • d) Review of major projects. In the review of a comprehensive permit application involving a major land development and/or major subdivision, the Planning Board shall hold a public hearing on the master plan and shall, within one hundred and twenty (120) days of issuance of the certification of completeness, or within such further amount of time as may be agreed to by the Planning Board and the applicant, render a decision. Preliminary and final plan review shall be conducted according to the Land Development and Subdivision Regulations except as otherwise specified in this section.
  • e) Required findings. In taking final action on an application, the Planning Board shall make positive findings, supported by legally competent evidence on the record which discloses the nature and character of the observations upon which the fact finders acted, on each of the following standard provisions, where applicable:
    • (1) The proposed development is consistent with local needs as identified in the comprehensive community plan with particular emphasis on the Town's affordable housing plan and/or has satisfactorily addressed the issues where there may be inconsistencies.
    • (2) The proposed development is in compliance with the standards and provisions of the Town's zoning ordinance and Land Development and Subdivision Regulations, and/or where expressly varied or waived local concerns that have been affected by the relief granted do not outweigh the state and local need for low and moderate income housing.
    • (3) All low and moderate income housing units proposed are integrated throughout the development; are similar in scale and architectural style to the market rate units within the project; and will be built and occupied prior to, or simultaneous with the construction and occupancy of any market rate units.
    • (4) There will be no significant negative environmental impacts from the proposed development as shown on the final plan, with all required conditions for approval.
    • (5) There will be no significant negative impacts on the health and safety of current or future residents of the community, in areas including, but not limited to, safe circulation of pedestrian and vehicular traffic, provision of emergency services, sewage disposal, availability of potable water, adequate surface water run-off, and the preservation of natural, historical or cultural features that contribute to the attractiveness of the community.
    • (6) All proposed land developments and all subdivisions lots will have adequate and permanent physical access to a public street. Lot frontage on a public street without physical access shall not be considered compliance with this requirement.
    • (7) The proposed development will not result in the creation of individual lots with any physical constraints to development that building on those lots according to pertinent regulations and building standards would be impracticable, unless created only as permanent open space or permanently reserved for a public purpose on the approved, recorded plans.
  • f) The Planning Board has the same power to issue permits or approvals that any local board or official who would otherwise act with respect to the application, including, but not limited to, the power to attach to the permit or approval, conditions, and requirements with respect to height, site plan, size, or shape, or building materials, as are consistent with the terms of this section.
  • g) In reviewing the comprehensive permit request, the Planning Board may deny the request for any of the following reasons:
    • (1) If the Town has an approved affordable housing plan and is meeting housing needs, and the proposal is inconsistent with the affordable housing plan;
    • (2) If the proposal is not consistent with local needs, including, but not limited to, the needs identified in its approved comprehensive plan, and/or zoning ordinances and procedures promulgated in conformance with the comprehensive plan;
    • (3) If the proposal is not in conformance with the comprehensive plan;
    • (4) If the community has met or has plans to meet the goal of ten percent (10%) of the year-round units in the Town as defined in § 45-53-3(4)(i) of the Rhode Island General Laws being low and moderate income housing; or
    • (5) If concerns for the environment and the health and safety of current residents have not been adequately addressed.
  • h) All Planning Board decisions on comprehensive permits shall be by majority vote of the membership of the board and may be appealed by the applicant to the State Housing Appeals Board.
  • i) If the public hearing is not convened or a decision is not rendered within the time allowed in Subsections B.4.c) and d), the application is deemed to have been allowed and the relevant approval shall issue immediately; provided, however, that this provision shall not apply to any application remanded for hearing, where more than one (1) application has been remanded for hearing provided for in § 45-53-6(f)(2) of the Rhode Island General Laws.
• 5. Appeal. Any person aggrieved by the issuance of an approval may appeal to the Supreme Court.
• 6. Expiration of comprehensive permits. A comprehensive permit shall expire unless construction is started within twelve (12) months and completed within sixty (60) months of final plan approval unless a longer and/or phased period for development is agreed to by the Planning Board and the applicant. Low and moderate income housing units shall be built and occupied prior to, or simultaneous with the construction and occupancy of market rate units.
• 7. Limit on comprehensive permit applications. The Town may limit the annual total number of dwelling units in comprehensive permit applications from for-profit developers to an aggregate of one percent (1%) of the total number of year-round housing units in the Town, as recognized in the affordable housing plan and notwithstanding the timetables set forth elsewhere in this section, the Planning Board shall have the authority to consider comprehensive permit applications from for-profit developers, which are made pursuant to this paragraph, sequentially in the order in which completed applications are submitted.
• 8. Annual reports required. The Planning Board shall report the status of implementation to the Housing Resources Commission pursuant to § 42-128-4 of the Rhode Island General Laws, including the disposition of any applications made under the plan, as of June 30, 2006, by September 1, 2006 and for each June 30 thereafter by September 1 through 2010, as further provided in Title 45, Section 45-53-4(4)(xiii) of the Rhode Island General Laws.
• 9. Remanded applications. Notwithstanding the provisions of § 45-53-4 in effect on February 13, 2004, to commence hearings within thirty (30) days of receiving an application remanded by the State Housing Appeals Board pursuant to § 45-53-6(f)(2) shall be heard as herein provided; in any town with more than one (1) remanded application, applications may be scheduled for hearing in the order in which they were received, and may be taken up sequentially from the date they are remanded, with the thirty (30) day requirement for the initiation of hearings, commencing upon the decision of the earlier filed application.

An applicant seeking approval of a comprehensive permit under the provisions of this article shall pay to the Town, upon submission of an application to the Administrative Officer, a filing fee to cover the costs of processing the application. The check shall be payable to the Town of Portsmouth.

[Added 12-14-2020 by Ord. No. 2020-12-14]

The Town Council finds that it is in the public interest and will ensure the health, safety, and welfare of the community through the safe, effective and efficient use of solar energy systems (SES) that minimize impacts on scenic, natural, cultural resources, increase resiliency, reduce the use of and reliance on fossil fuels for power production, reduce carbon and other greenhouse gas emissions of utility-supplied electric energy, and provide clean, domestically-sourced alternatives to our existing energy supply.

The purpose of this section is to permit and facilitate appropriately scaled solar energy systems and to establish criteria and development standards that maximize their effectiveness and efficiency while addressing potential negative impacts in various zones throughout Town. A solar energy system is a method of generating electrical power by converting solar radiation into direct current electricity using semiconductors that exhibit the photovoltaic effect. Photovoltaic power generation employs solar panels composed of a number of solar cells containing a photovoltaic material.

All solar energy systems shall require reviews, and approvals as outlined in this article. Solar energy systems must be consistent with all applicable state and federal fire and electrical safety codes and shall obtain all necessary statewide solar, building, and electrical permits from the Building Official prior to commencement of construction.

There are four categories of solar energy systems contemplated by this zoning ordinance, and they are as follows:

• 1. Roof-mounted system: a solar energy system that is accessory to a primary structure. An accessory roof-mounted system shall be installed only on the roof of a structure.
• 2. Small SES: a ground-mounted solar energy system that is an accessory use to the primary structure use. A small system shall consist of no more than 1,600 square feet of solar panel surface area.
• 3. Medium SES: a ground-mounted solar energy system that is the primary use or an accessory use of a lot or lots which may be designed to produce more energy than consumed by the primary use of the property as a secondary use. A medium system shall consist of more than 1,600 square feet of solar panel surface area, but equal to or less than 40,000 square feet of solar panel surface area.
• 4. Large SES: a ground-mounted solar energy system that is the primary use or an accessory use of a lot or lots which may be designed to produce more energy than consumed by the primary use of a lot or lots as a secondary use. A large system shall consist of more than 40,000 square feet of solar panel surface area.

See Article V, Section J.

• 1. Height requirement:
  • a) Ground-mounted SES: The maximum height must not exceed 12 feet from existing grade.
  • b) Building-mounted SES: The total height of the building and photovoltaic panel must not exceed the maximum building height regulation for the zoning district per Article IV, Section B.
• 2. Yard setbacks and vegetative buffer area requirements:
  • a) Small SES: Yard setback areas are as required by Article IV, Section B, Land Use Requirement Table.
  • b) Medium and large SES:
    • i. Yard setback areas must maintain one-hundred-foot (100') minimum setbacks on all sides, and one-hundred-fifty-foot (150') minimum setbacks on all sides that abut residentially zoned property. Where this standard conflicts with the requirements of yard setbacks in Article IV, Section B, this standard is to supersede.

      [Amended 11-8-2021 by Ord. No. 2021-11-2008]

    • ii. Vegetated buffer areas must be a minimum of thirty feet (30') within the yard setback where abutting residential and Town Center (C-TC) zones and a minimum of twenty feet (20') within the yard setback where abutting all other zones.
• 3. Lot coverage:
  • a) Small SES: The lot coverage for a small system shall follow the individual zoning district regulations. The lot coverage calculations will be a sum of the area of each individual panel's outer dimensions as if lying flat on the ground plus the footprints of all other countable structures under this article.
  • b) Medium and large SES: Medium and large systems shall meet the setback and screening requirements, and site plan review; otherwise, there is no lot coverage limitation. This exemption is not intended to apply to municipal stormwater regulations, as the panels could have the effect of altering volume, velocity, and discharge pattern of stormwater runoff.
